| Abstract |
In this paper, we analyzed the risk factors in the heat exchange rod manufacturing plant of a thermal power plant and proceeded with research to find a solution. The problems of all 11 processes were analyzed, and each process consisted of tube loading, tube sanding, high frequency welding, rust prevention, in-process inspection, cutting, banding, banding inspection, packing, pre-shipment inspection, and shipping process. Worker safety equipment was recognized through video analysis in order to prevent worker safety accidents. The YOLOv5 algorithm was used for image analysis, and 1000 images were labeled as training data and used as a training, validate, test set at a ratio of 7: 2: 1. The risk factors in the process and the video analysis method for solving the problem will be explained concretely. |
